We've had great luck using 32MB SIMMS in our UDB's. Admittedly, an error
in addressing (when crossing over the 64MB boundary) pops up after a warm
boot, but a cold boot clears this right up.

You might make sure the SIMMS have no more than 24 chips on them; I don't
know about the UDB's but I've seen many boxen that won't map anything
with > 24 chips.

I tried running INN under RH 4.0 as ELF last night; no problems that I
could see. Unfortunately, I didn't have much of a news spool set up, so
I'm not sure how memory intensive the feed was; the memory load seemed
I didn't notice in your posting if you were sure the 8x36 SIMMS were
"true" parity. Logic parity SIMMS will cause most (if not all) AXP's to
